ImmuneSense™ COVID-19 Study

Comprehensive diagnostic testing has an important role to play in the control and containment of the current pandemic. Adaptive Biotechnologies Corporation (Adaptive) has developed an immunosequencing technology, called immunoSEQ®, which utilizes polymerase chain reaction (PCR) and next-generation sequencing (NGS) to identify and quantify rearranged T-cell receptor (TCR) gene sequences from peripheral blood, collectively referred to as the T-cell repertoire. The T-cell repertoire can be further analyzed using indication-specific algorithms that are based on disease-associated TCR sequences.

Adaptive has developed a clinical test called T-Detect™ SARS-CoV-2, which is intended to identify a T-cell response to the SARS-CoV-2 virus, indicating recent or prior infection. In this investigational study, Adaptive plans to clinically validate samples acquired from patients with COVID-19 and present results for an eventual EUA-submission for the T-Detect™ SARS-CoV-2 Assay. T-Detect™ SARS-CoV-2 is a single-site assay performed at Adaptive Biotechnologies Corporation.

Inclusion criteria

Participants must satisfy the following criteria to be enrolled in the study:

• Currently symptomatic individuals who are being tested for SARS-CoV-2 infection by nasopharyngeal swab
• Male and female participants of any race and ethnicity between 18 to 89 years of age (inclusive) at the time of enrolling in the study
• Must be able to communicate with the investigator, understand, and comply with the requirements of the study

Exclusion criteria

The presence of any of the following will exclude a participant from enrollment:

• Asymptomatic individuals who are being tested for SARS-CoV-2 infection
• Prior confirmed diagnosis of COVID-19
• Any person who cohabitated with another individual with known COVID-19
• Protected populations including minors, pregnant women, prisoners, mentally disabled persons, and wards-of-the state
• Any significant condition, laboratory abnormality, or psychiatric illness that would prevent the participant from safely participating in the study
• Donated more than 500cc or 1 pint of blood in the past 60 days prior to the blood draw
• Participation in a COVID-19/SARS-CoV-2 study or received a COVID-19 vaccine, antibody, or other COVID-19 therapeutic Investigational drug or compound that will impact results of the study at the discretion of the investigator, such as but not limited to a COVID-19 antibody, therapeutic, or other medication that will impact the person's immune system
